You get funding equal to the length of your course plus one year usually, so provided that you've been using the same course code to apply for finance for each year since your foundation year, you should still have the "gift year" available if required.
Note however you generally can't choose to resit a year - your uni will tell you if this is required. Likewise you usually can't resit exams at uni to improve your grade (normally individual exam resits are capped at the lowest pass mark). Your uni may have a "no detriment" policy due to the covid situation - I'd suggest speaking with your personal tutor about this and your current situation and what options you will have.
